National identification card (Taiwan)
The national identification card is a compulsory identity document issued to people who hold both nationality law|nationality] and household registration in Taiwan. The National Identification Card served as the evidence for the household registration in Taiwan which grants the holder the right of abode and full civil and political rights in Taiwan. The card is used for virtually all other activities that require identity verification within Taiwan such as opening bank accounts and voting.
Despite the name mentioning "national", not all nationals regulated by Taiwanese nationality law are eligible to apply for an ID card. Nationals without household registration are not qualified for an ID card. These people, mainly overseas Taiwanese or overseas Chinese, are only eligible to apply for a Taiwan passport. They will need to apply for an Exit & Entry Permit or Resident Certificate if they want to perform short-term visit or long-term residency in Taiwan respectively.
Eligibility
The national identification card is issued to nationals with household registration in Taiwan. Establishing household registration in Taiwan is required for a national over 14 years of age to possess a National Identification Card. In Taiwanese laws, household registration has close ties to exercise civil and political rights like a citizen. The Taiwanese laws makes a distinction between "nationals with household registration" and "nationals without household registration", with the former having the right of abode, right to vote, and other benefits of citizenship, while the latter are subject to deportation from Taiwan and need an entry permit to visit Taiwan. While NWHR are entitled to hold the National Identification Card, NWOHR may only hold the Taiwan Area Resident Certificate. Both groups are eligible to hold the Taiwan passport. The Taiwan Area Resident Certificate is nearly identical to the Alien Resident Certificate held by foreign residents in Taiwan.Anyone under the age of majority in Taiwan, one of whose parents was an NWHR at the time of birth, could direct establish household registration.
Adult NWOHRs with direct lineal relatives who are NWHRs are eligible to apply for the aforementioned TARC and are eligible for household registration after residing in Taiwan for a certain period of time. Currently, this period is continuously for one year, 270 days per year for two years, or 183 days per year for five years.
In 2024, new amendments to the Immigration Act passed in 2023 took effect, which dramatically loosened restrictions on children of NWHRs to establish household residency. In particular, adult NWOHRs, at least of whose parents was a NWHR at the time of birth, were eligible to directly establish household registration. While this eliminated the legal distinction with respect to eligibility for household registration between underage and adult NWOHR children of NWHRs, there remain several administrative differences to actually register, such as the requirement for the adult NWOHR to enter Taiwan on an NWOHR passport.
For foreigners who have naturalised as ROC nationals as well as all other holders of TARCs, the above periods of time also apply after they receive their TARCs before they are eligible for household registration.
Usage
The Identification Card contains the holder's photo, ID number,Chinese name, and date of birth. The back of the card contains more detailed information, including the person's registered address where official correspondence is sent, as well as the names of his/her legal ascendant. If the person moves, he/she must re-register at a municipal office.
Unlike the Republic of China passport which can be issued overseas at Taipei Economic and Cultural Offices and ROC embassies and consulates, the National Identification Card is only issued in Taiwan at district, municipal, and township offices. Male dual passport holders who register for household registration and the Identification Card also become eligible for military conscription within the Republic of China, unless the person has overseas resident status.
Possession of the Identification Card is required to obtain the People's Republic of China's Taiwan Compatriot Permit for entry into Mainland China. Most countries granting visa-free entry for ROC passport holders require that the passport holder also possess a National Identification Card. Those without National Identification Cards will have the National Identification Card field blank in their passports.
